So yesturday I installed and reflashed the car for the COBB SF intake and airbox. WOW what a difference. The BPV now has a sort of BOV sound to it, to satisfy those who enjoy that sound, but not too overpowering to be un-enjoyable for those who don't. I love how it hisses when boosting, and it now boosts alot quicker. Deff. worth the price. Ill soon be writing a build log.
